Today, we offer a complete line of HVAC dampers and air control products including volume control, balancing, round, zone, fire, smoke and combined models. Some dampers are adjustable metal plates installed inside of a duct to close off or control the volume of heating and air conditioning in a specified room or area. Their applications cover Oxidizers, Baghouses, Scrubbers, Heaters, Precipitators, etc. Guillotine dampers are best known for their capability to provide the best Seal possible. These dampers are normally opened by the force of the spring but can be closed by the force of the motor. The flow can be controlled with the help of set screw provided on the damper handle to regulate the desired air flow. Such dampers are known as zero leakage bubble tight damper, volume control damper, motorized volume damper, etc. Install volume control dampers in lined duct with methods to avoid damage to liner and to avoid erosion of duct liner. Doing this will improve efficiency and occupant comfort. In either case, the motor is usually connected to the damper via a mechanical coupling. Dampers for HVAC applications have many variations and you can operate them through different means including manual, mechanical and automatic methods. These dampers facilitate the air flow to each zone and each room to be controlled during testing & commissioning. These volume control dampers are installed in branches of Air Distribution duct. Control dampers are typically installed inside ductwork with low- to medium-airflow velocity. * Volume Control Dampers allows even distribution and flow control of air at high duct pressures and are suitable for various type of HVAC applications. Based on 2015 IMC, ASHRAE & SMACNA. Damper rectangular, for pressure and volume flow control in HVAC-systems, casing made of galvanized steel. This type of dampers is particularly used for its quick response time and strong air blocking properties. HVAC systems are typically divided up into multiple zones. Volume control damper can be mounted either horizontally or vertically. Fax: 561-547-4022 Cable operated dampers are adjusted via … Another style of electrically powered damper uses a spring-return mechanism and a shaded-pole synchronous motor. Highly sophisticated systems may use some form of building automation such as BACnet (building automation and control networks) or LonWorks (local operating network) to control the zone dampers. These dampers will also allow adjustment of the “closed” position so that they only obstruct, for example, 75% of the air flow when closed. Volume damper for the HVAC system offered by Biyang features high tensile strength, application-specific, and guaranteed to provide many years of reliable service life. Volume Control Damper Achieve simple and cost effective manual flow control application with the Wozair Volume Control Damper (VCD). Volume control dampers by Biyang is intended to help you maximize energy efficiency and minimize installation cost. Fax: 407-279-5501 Blade dampers are designed for amazing metering and control. Its operation can be manual or automatic. Air Dampers – Perfect for a Wide Variety of Applications At Johnson Controls, we offer Damper Controls in a diverse range of models. In large commercial installations, vacuum or compressed air may be used instead. flow resistance and noise; coupling and drive possibilities for all requirements, high This site uses Akismet to reduce spam. The DAYTON® volume control damper helps regulate the volume of air moving through a duct system. These dampers can be fixed within the duct itself and can be automatic or manual. Removal of electrical power re-opens the damper. Below are 7 damper types used in hvac […]. Volume control damper can be mounted either … The location of a damper, its ducting structure and itâs the purpose all together determine the type of it. It can be used as a positive shutoff, and can also be used for automatic control in low-leakage HVAC systems, or systems requiring modulating airflow. EB Air Control Inc. was incorporated to providing highest quality solutions for HVAC and related industries with strong characteristics towards design and technology for âindoor air comfort and qualityâ. PRODUCT DESCRIPTION . Automatic or motorized dampers may also be controlled by a solenoid, and the degree of air-flow calibrated, perhaps according to signals from the thermostat going to the actuator of the damper in order to modulate the flow of air-conditioned air in order to effect climate control.(source). They can be used as positive shutoffs, and can also be used for automatic control in low-leakage HVAC systems. HVAC dampers can monitor air flow, temperature and humidity throughout homes and buildings.
